Preparation of vinylphenols from 2- and 4-hydroxybenzaldehydes

A straightforward, high-yielding procedure has been developed for the manufacture of substituted vinylphenols from 2- and 4-hydroxybenzaldehydes utilising classical Knoevenagel condensation reaction conditions.

Non-natural cinnamic acid derivatives as substrates of cinnamate 4-hydroxylase

Cinnamate 4-hydroxylase (C4H), a monooxygenase in the plant phenylpropanoid pathway, was assayed for its ability to hydroxylate 29 substrate analogues. Nine of the tested analogues with various aromatic side chains, including 3-coumaric acid, were metabolized by C4H. Seven products from these reactive analogues were characterized using LC/MS, 1H NMR and 13C NMR spectroscopic analysis. For example, caffeic acid was the product of 3-coumaric acid. The products 4-hydroxy-2-chlorocinnamic acid and 4-hydroxy-2-ethoxycinnamic acid are novel compounds that have not been previously reported. The kinetic parameters of C4H towards these analogues were determined.
